Objects are not counted in the header and will not export
Only objects which are in visible Scene layers are counted in the info header.  

Note the difference between Scene layers and View layers:


View layers are set in 3D view > Header, and are independent between different 3D view editors. Only objects in the the current 3D view's view layers are shown in that 3D view.
Scene layers are set in Properties > Renderlayers > Layer > Scene, and control the visibility of objects for the enter scene. This visibility is used for scene-wide operations such as renders and exports.


By default these two layer sets are locked together so that they are always set to the same layers, however this option is disabled in your file (1).

Either re-enable this option, or set the scene layers to match your view layers in the header of the 3D view (2).
